131 MiB checkpoint window `[0x80300000, 0x88600000)`.

The full capability block describes XiangShan hardware and is not fully
emulated by the current QEMU `nemu` machine. In particular, DT-advertised
`smrnmi` requires an OpenSBI platform `smrnmi_handlers_init` callback, while
the `nemu` timer path cannot execute the DT-advertised `sstc` CSR sequence.
The current multi-core DTB must omit `smrnmi` and `sstc` and run with
`sstc=false`.
supported by the current OpenSBI generic platform and QEMU `nemu` machine.
DT-advertised `smrnmi` requires an OpenSBI platform
`smrnmi_handlers_init` callback, which the generic platform does not provide.
All single-hart and multi-hart DTBs used with the generic platform must omit
`smrnmi`. In addition, the current multi-core `nemu` timer path cannot execute
the DT-advertised `sstc` CSR sequence, so multi-core DTBs must omit `sstc` and
run with `sstc=false`.

The build does not invoke this generator automatically. Run it and review the
result before building with the corresponding `HARTS` value.
